SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyzes the blast radius of a code change by locating all call sites, test mocks, and consumers, helping teams reason about impact before modification.

Core Features & Use Cases

Identify function, class, or file definitions across a codebase.
Find all call sites and downstream dependencies to understand ripple effects.
Detect and enumerate test mocks and integration points that rely on target APIs.
Use cases include safely updating shared utilities, services, or interfaces with minimal risk.

Quick Start

Provide a target function, file, class, or method name to analyze its blast radius.

FAQPage Schema

How do I analyze the blast radius of a function before modifying it?▼

To analyze blast radius, parse the target function definition to locate all call sites, identify test mocks, and map downstream dependencies, generating a risk-aware report of ripple effects before modification.

What is code change impact analysis and when do I need it?▼

Code change impact analysis discovers all consumers, call sites, and test mocks relying on a target API or file. You need it to safely update shared utilities, services, or interfaces with minimal risk of breaking downstream components.

How do I find all call sites and test mocks for a shared utility?▼

Finding call sites and test mocks requires parsing the target utility definition and scanning API services, modules, and tests to enumerate integration points and downstream dependencies that rely on the target APIs.

Can I use dependency analysis to check ripple effects across API services and modules?▼

Yes, dependency analysis maps downstream components across API services and modules by locating all call sites and consumers, helping you understand the full ripple effect of a code change before applying it.

What's the best way to map downstream dependencies before updating a class or file?▼

The best way to map downstream dependencies is applying impact analysis across the codebase to identify definitions, locate call sites, detect test mocks, and map consumers, delivering a risk-aware report for safe updates.

What are the limitations of impact analysis for complex codebases?▼

Impact analysis limitations depend on accurately parsing definitions and locating call sites; if mocks or downstream consumers are dynamically loaded or hidden behind integration points, the risk-aware report may miss those ripple effects.
